I’ve set registration to Require application again, don’t like this bots creating accounts.
Also I’m running into email limitations. Using the Sendgrid Free plan of 100 emails per day, but if a couple of member have email notification on, I’m reaching that 100 very quickly. How do others handle the high email traffic ?
Wouldn’t it help to force registrations solve an expensive proof of work on the client side?
That would probably only slow them down. And since their main goal is to create a ton of working accounts, speed is probably not that important to them. On my own instance the bot-registrations stopped immediately after I enabled the required application.
